Spiral Point Tap 1/4 -28 HSS
The Spiral Point Tap 1/4 -28 HSS is an essential tool for professionals requiring precise thread cutting operations in various industries such as aerospace, automotive, and manufacturing. With its quarter-inch diameter and twenty-eight tpi, it is suitable for diverse applications that require accurate threads. The spiral point design ensures greater chip clearance while reducing breakage during use, making it ideal for high-precision tasks.
UN fine (UNF) taps have more threads per inch than UN coarse (UNC) taps. Compared to UNC taps, UNF taps perform better in threading applications on thin-walled workpieces and hard materials. Fine threads provide more tensile strength and shear strength than coarse threads. The bright finish on these taps provides a smooth, polished surface.
